On my program i am trying to make a activation form, so in order the program to activate the user has to enter a product code on the package but. I know how to code it and everything but I have the code put a "-" every 4 characters that the user types, but now i need it to add a "-" every 5 character that the user types. Here is the code:

Dear Experts modify UPDATE codes according to INSERT codes Style.
[Code].....
I need update codes as there are insert codes
Just looking at various ways to do so.I came accross an article which unfortunatly I can't find anymore. It explained it like this. (I'll try remember all of it)1) Put activation key in textbox12) Press button3) Checks with the FTP server if the title of a file (In the this case the license key) in the FTP server.4) If the file doesnt exist then a message box comes up incorrect license.4b) I the file does exist then my.settings.activate = 15) Next time its loaded up, the program checks if my.settings.activate = 15b) If not then an activation key must be put in and proccess starts again.
View 6 Repliesi have installed my program on several computers and it works but for some reason on this one computer it doesn't work.i attached the error log. i can't figure out why it won't run. it installs ok.
View 6 RepliesLet's say we have a controltab with two tab. The first tab contains textboxs where entry values are entered On the second tab are textboxs that display the results. I have noticed that if I fill up the entry values and create the binding between each textbox and their property and then I destroy it (without clearing the textboxs), the textboxs of the second tab will not display any result. I have this exemple here BindingAddition.rar

An application I'm working with registersun-registers a group of dll's using regsvr32.
System.Diagnostics.Process.Start("regsvr32", "somedll.dll /s")
This worked fine on Pre Vista systems but this will not work on Vista7 due to UAC.
Is there an alternative method to register dll's programatically without needing elevation?
If it help's the dll only needs to be registered for the current user, could adding details to the registry directly solve this?
(The application runs several versions of a legacy application, these dll's are swapped out depending on the version being loaded)
I have devices with unique serial number (string incremetation) ex : AS1002 and AS1003. I need to figure out an algorithm to produce a unique activation key for each serial number. What would be the best approach for this ?
View 5 RepliesI have made some custom .dll's or components and then I downloaded custom webkit component and it didn't work perfectly(I mean that I always get some error code with this error: An error occurred creating the form. See Exception.InnerException for details.The error is: Failed to initialize activation context. When I try to debug the project). And if I have made a new project, and make a component with user control, and I haven't saved it yet, it will work fine, but until I save it then it will give me a designer error.

View 1 RepliesI am going to publish my program soon. As for the product serial activation, I have combined the user machine's CPU ID and the MAC Address to make a formula. Here is the class code to find processor ID and MAC which I have found on net and used :
Friend Function GetProcessorId() As String
Dim strProcessorId As String = String.Empty
Dim query As New SelectQuery("Win32_processor")
Dim search As New ManagementObjectSearcher(query)
Dim info As ManagementObject
[Code] .....
There a few questions I want to ask to be sure about my program activation :
- These 2 function code, Are they safe to use ? Is there any possibility that one of them or both doesn't return anything ? ( because of user permissions,os type, etc...)
- Is it possible that somehow the user machine won't have MAC Address?
- Is Proccessor ID a Unique serial for each machine in the world?
In Excel 2010 (but also in older versions you can find a nice functionality - auto filter. When you just put some data in a row and press CTRL+SHIFT+L you activate Auto Filter. Now you press the down arrow and you get what I need... A new window appears. This window include buttons ordered in something like a context menu a textbox and a checkedlistbox. The windows definitely is not a classic form, because when you operate with the controls on it, the original excel windows is still the active window. The window can also be drawn outside of the main excel windows.
View 5 RepliesI have created an Excel Ribbon Addin that has some custom features that will benefit a relatively small business niche. The target companies number less than 1,000.I don't want to limit any one company's usage of the Addin...meaning I want them to be able to install and use the Addin as often as they need to, for as long as they need to, on as many computers as they need to.
The thing I want to prevent is sharing of the Addin. There are family members in this industry, that own different companies in different parts of the country...there are close friends in this industry that each own different companies. I want each company to purchase the Addin instead of share it.I have created a License Agreement that they have to agree to before the Addin is installed. But, that is as far as I have gone with it at this point.So, this leads me to 2 questions:
1. Is it worth the investment and effort to create this type of limitation for such a small market?
2. If so, what is the best way to go about accomplishing this?
This is how I handle online activation for my application the problem is that this is very poor security because i display my Username and Password. I was thinking of using Myslq but i also have to input the Username and the password into the application. What other ways do big companies like Kaspersky handle online activation.

It's being some years since i actually wrote a program in VB, last time was VB 6.So it's being a long time, and things have changed a bit.And i am still very rusty, so i need to get back into it.I got a few problems which i cant remember very well.1st question.I got several text boxes, in these text boxes there will be prices of products.The very last text box is inactive, and is supposed to show the total of all of the above.I have to declare the text boxes to contain numeric values only, so there will be no mistake when doing the calculations.But i cant remember what it was, and what the best option is to add up all the values from the text boxes.
View 2 RepliesEssentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

View 3 RepliesI need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text

With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.
1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?
2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?
I'm making an application that will change position of two characters in Word.

Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.
I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time. Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

So I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?
